Chrysanthemum plant named ‘PPP UNY 09’

ABSTRACT

A new and distinct  Chrysanthemum  plant cultivar is disclosed, characterized by small daisy type inflorescences, consistent flowering response to short days, blooming consistently after 49 days of short day length, yellow ray florets, free branching habit, and a consistent natural season flowering habit during the third week of September.

Latin name of the genus and species: Chrysanthemum morifolium.

Variety denomination: ‘PPP UNY 09’.

BACKGROUND OF THE INVENTION

The new cultivar ‘PPP UNY 09’ is a product of a cross between the male parent ‘Yellow Urano’ (U.S. Plant Pat. No. 13,101) and the female parent ‘GEM ONE OST’ (U.S. Plant Pat. No. 13,868). The new cultivar was discovered and selected by Dirk Pieters in October of 2000 in a greenhouse in Oostnieuwkerke, Belgium.

Asexual reproduction of the new cultivar ‘PPP UNY 09’ by terminal cuttings was performed in Oostnieuwkerke, Belgium and Oxnard, Calif., and has shown that the unique features of this new cultivar are stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘PPP UNY 09’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘PPP UNY 09.’ These characteristics in combination distinguish ‘PPP UNY 09’ as a new and distinct Chrysanthemum cultivar:

-   -   1. Small, yellow, daisy-type inflorescences;     -   2. Consistent natural season flowering habit during the third         week of September;     -   3. Free branching habit; and     -   4. Consistent flowering response to short days, blooming         consistently after 49 days of short day length.

Plants of the new cultivar ‘PPP UNY 09’ are similar to plants of the male parent variety, ‘Yellow Urano’ in most horticultural characteristics, however plants of the new cultivar ‘PPP UNY 09’ have a more solid daisy inflorescence form compared to the decorative inflorescence of ‘Yellow Urano’, which opens to a multiplex daisy. Also, the new cultivar ‘PPP UNY 09’ has a smaller inflorescence diameter and longer inflorescence longevity. Additionally, the ray florets of ‘PPP UNY 09’ are a different color yellow than the male parent. Finally, ‘PPP UNY 09’ naturally blooms two to three weeks later than the male parent ‘Yellow Urano’.

Plants of the new cultivar ‘PPP UNY 09’ are similar to plants of the female parent variety, ‘GEDI ONE OST’ in most horticultural characteristics, however plants of the new cultivar ‘PPP UNY 09’ are shorter but have a wider plant spread. Also, the new cultivar ‘PPP UNY 09’ has a smaller inflorescence diameter. Additionally, the ray florets of ‘PPP UNY 09’ are a different color yellow than the female parent. Finally, ‘PPP UNY 09’ naturally blooms one week earlier than the female parent.

In comparison to the commercially available variety ‘GEDI YP’ (U.S. Plant Pat. No. 11,238), ‘PPP UNY 09’ is shorter and wider. Additionally, the new variety ‘PPP UNY 09’ has a larger inflorescence diameter and lighter yellow ray florets. Further, the new variety ‘PPP UNY 09’ has more ray florets per inflorescence. Finally, ‘PPP UNY 09’ blooms one week earlier than the comparable variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in the drawing illustrates in full color a typical plant of ‘PPP UNY 09’ grown in a 2 gallon container. One cutting was used in the pot, planted mid May and grown under outdoor field conditions. The colors are as nearly true as is reasonably possible in a color representation of this type.

-   Disease resistance: Neither resistance nor susceptibility to     diseases or pests has been observed in this variety. -   Drought tolerance/cold tolerance: Flowering plants are hardy to low     temperatures about −2° C. Non-flowering plants are hardy in the     approximate range of 3° C. to −6° C., depending upon duration of     cold and amount of moisture in the soil. With adequate water plants     are hardy to a high temperature of 45° C. -   Fruit/seed production: Commercially, this plant is not used or     observed in a stage where seeds would be produced. Therefore, seed     production has not been observed.
